2. Principles of Operation

The System consists of an Airbag Control Unit (with built-in sensors) integrated into the back
protector, (Figure 1). The cluster of sensors consists of 3 accelerometers and 3 gyroscopes.
These six sensors monitor the user's body for shocks or unexpected movements. In the
event the user's body is subject to a high and/or sudden amount of energy, the System will
deploy. This may occur when the motorcycle is involved in an accident, such as when the
motorcycle collides with another vehicle or object, when the rider loses control or when the
rider falls off the motorcycle.
The System is equipped with a Bluetooth Low Energy (BLE) device located in the electronic
control unit. The BLE allows the System to connect directly to a mobile phone in order to
receive important information from the System, while also permitting the users to access
a number of other functions (for further information see "Tech-Air® App" in Section 17).
To connect the System to the mobile phone via Bluetooth, remember to
activate the Bluetooth module within your phone and to download the Tech-
Air® App available at Android Play Store or at Apple Store.

3. Tech-Air® Envelope of Protection
In general, there are three basic factors that determine whether an airbag system will
provide protection to a user:
• Whether the forces experienced by the user during an event (such as an accident) occur
within an area covered by the airbag; and
• Whether the airbag deploys before the user collides with a vehicle, an obstacle or the
ground.
• Whether the airbag deploys before the user collides with parts or accessories of his/her
own motorcycle. For example, mirrors, windscreens or tank bags.
To provide protection to a user, an airbag system must be fully deployed. The deployment
time consists of the time for the sensors to detect the dangerous event, plus the time it
takes to fill the airbag fully with gas, which, for the System is about 40 milliseconds (ms)
maximum. The time to deploy the airbag depends on the type of accident, the type of
motorcycle (e.g. scooter, custom, sports) and the speed involved, amongst other things.
The "Envelope of Protection" is a term used to generally describe situations and/or
circumstances where the System may provide protection denoted as "inside the Envelope",
and those where it will not, denoted as "outside the Envelope".
The System protects both the rider and the passenger wearing the System in the event of
an accident or other triggering events; however, like any other product, there are limitations
to the protection it can provide.
WARNING! No product can provide complete protection from injury (or death),
or damage to persons or property in the event of a fall, accident,
collision, impact, loss of control or other event.

The System provides impact protection for those areas where airbag coverage is shown in
Figure 2.

WARNING! The System provides only limited impact protection against forces in
the areas of airbag coverage as depicted in Figure 2. No guarantee is
given that the System will prevent injuries (including severe or fatal
injuries) inside and/or outside the areas of airbag coverage or the
Envelope of Protection.
WARNING! The System cannot prevent accidents or injuries to the user.
WARNING! No protective device, including the System, can provide protection
against all possible sources of injury and therefore cannot provide
complete protection against injuries.
For Tech-Air® 5 System the Envelope of Protection includes crashes against obstacles and
loss of control crashes (commonly referred as 'low-side' and 'high-side').
IMPORTANT!
There are some limitations on the deployment of Tech-Air® 5 System
even inside the Envelope of Protection (like a high impact angle on a crash
against an obstacle, or low impact forces). In general, the System is not
expected to deploy if the impact energy is too low.
Envelope of Protection for Crashes Where a Vehicle Strikes a Stationary
Motorcycle:
Arrival Speed From 25km/h (15mph)
Impact Angle From 45° to 135°
The above parameters are valid for both rider and passenger.
